lllll rfa Patented Nov. 28, 1933 PATENT! OFFICE CAR RooF Charles Davidv Bonsall, Pittsburgh, Pa., assignor.

to P. H. Murphy Company,

New Kensington,

Pa., `a corporation of Pennsylvania Claims;

The subject matter hereof is divided out of my pending application-Serial No. 475,866, led August 18, 1930, for patent for car roof.

The present invention relates to car roofs, par- 5 ticularly to rigid car roofs ofthe type wherein themetal roof sheets have their adjacent margins rigidly secured together and to thek tops of interior carlines.

The present invention has for its principal objects to provide improved means for securing an insulating llining to the undersides of the'roofs of the above typeand to provide for simplicity and cheapness of construction and the easy application of said lining to the roof. The invention consists principally in the insulated roof construction and in the construction, combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specication and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan view of a portion of an insulated car roof embodying my invention, portions of the roof sheets being shown broken away to disclose the parts located therebelow.

Fig. 2 is a vertical transverse section throughA one-half of the roof on the line 2--2 in Fig. 1,

Fig. 3 is a vertical longitudinal section through the roof on the line 3-3 in Fig. 1; and

Fig. 4 is a fragmentary vertical section through the roof on the line 4 4 in Fig. 3.

The present roof comprises side plates l that are connected by inside carlines 2 preferably of substantially inverted channel-shaped cross-section with outwardly projecting base flanges 3 at the lower edges of their side walls. The side plates 1 are shown in the form of Z-bars preferably arranged with theirwebs horizontal and with their inner flanges extending upwardly. The carlines 2 are deepest at the ridge and gradually decrease in depth toward the eaves where they are provided with depending end lianges 4 that overhang and are` rigidly secured to the outer faces of the upstanding inner flanges of the sideplates 1.

lapped and rigidly secured together and to thev flat tops of the inverted channel-shaped carlines 2 by rows of rivets 8.

Metal roof sheets 5 extend transversely of the A -running board 9 extends longitudinally of thecar at the ridge and is supported on the lateral top flanges of 4Z-shaped running. board sadvdles 10, whose lateral base ilanges rest on the roof .sheets above the carlines 2 and are rigidly 60 secured to vsaid carlines by the rows of rivets 8 thatrsecure theY lapped margins of said sheets thereto. f

\ Wooden members or strips `11 extend from side plate to side plate midway between adjacent carlines with theirlower surfaces in theplane of the lower surfaces of said carlines. These wooden strips 11 are removably secured to the undersides of the roof sheets preferably by means of hangers or brackets in the form of metal straps 12 that 70 are preferably located adjacent to and inter-V mediate between the'ridge and eaves of the roof. The metal straps 12 are disposed crosswise to the wooden strips lland have their ends riveted to the undersides of the roof sheets. Fastening members, preferably in the form of boltsV 13, depend from the metal'straps 12, whose middle portions are perforated to receive said bolts and are offset downwardly, as at 14, to accommodate the heads at the upper ends thereof. The bolts 13 extend downwardly through wooden strips 11 and are threaded atV their lower ends to receive nuts 15. The bolt holes in the wooden strips 11 have their lower ends countersunk to receive the nuts 15; and the upper surfaces of said strips 85 are grooved crosswise, as at 16, to accommodate the bolt hanger straps. 12.

The wooden strips 11 serve as nailing strips for attaching an insulating lining to the underside of the roof. This insulating lining pref- 90 erably comprises tongue-and-groove boards 17 that extend longitudinally of the roof beneath the carlines 2 and nailing strips 11 and are nailed or otherwise secured flatwise to the bottoms of the latter. If desired, the insulating lining may also be secured to the carlines in any desired manner, such as for instance, in the manner shown in my pending application hereinbefore referred to.

The hereinbefore described arrangement perlines, members extending from side plate to side plate between carlines, an insulating lining located beneath said carlines and members and secured to the undersides of the latter, and means for securing said members to said roo sheets, said means comprising brackets rigidly secured to the undersides of said roof sheets, and means for attaching said members to said brackets.

2. A car roof comprising side plates connected by carlines, roof sheets rigidly secured to said side plates and carlines, wooden strips extending from side plate to side plate between carlines, an insulating lining located beneath said carlines and wooden strips and secured to the undersides of the latter, and means for securing said wooden strips to said roof sheets, said means comprising straps disposed and riveted to the undersides of said roof sheets, and bolts for securing said wooden strips to said straps.

3. A car roof comprising side plates connected by carlines, roof sheets rigidly secured to the tops of said carlines,.wooden strips extending from side plate to side plate between carlines,

an insulating lining located beneath said car-` lines and wooden strips and secured to the undersides of the latter, and means for securing said wooden strips to said roof sheets, said means comprising straps disposed crosswise of said nailing strips with their endsriveted to the undersides of said roof sheets, and bolts for securing said wooden strips to said straps.v

4. A car roof comprising side plates connected by carlines, roof sheets spanning the spaces between carlines, wooden strips extending from side plate to side plate between carlines, an insulating lining located beneath said carlines and wooden strips and secured to the undersides of the latter, and means for securing said wooden strips to said roof sheets, said means comprising straps disposed crosswise or said wooden strips with their ends riveted tc the undersides of said roof sheets and with the portions intermediate their ends oiset downwardly, and fastening devices mounted in the downwardly oiset portions of said straps and removably engaging said wooden strips.

5. 'A car roof comprising side plates connected by Vcarlines, roof sheets spanning the spaces between carlines, wooden strips extending from side plate to side plate between carlines, an insulating lining located beneath said carlines and wooden strips and secured to the undersides of the latter, and means for securing said wooden strips to said roof sheets, said means comprising straps disposed crosswise of said wooden strips with their ends riveted to the undersides of said roof sheets and with the portions intermediate their ends offset downwardly, and bolts depending from the downwardly oiset portions of said straps and removably engaging said wooden strips.
